Breeding management 101 — Who, what, where, when, and why (Proceedings)


CVC IN BALTIMORE PROCEEDINGS


Objective

The objective of this session is to provide the practitioner with the knowledge required to effectively manage a canine breeding.

General key points

          - WHO - Counseling your clients in their selection of breeding candidates
          - WHAT - Making a recommendation as to type of breeding
          - WHEREDetermining the sperm cell deposition site
          - WHEN - Planning the breeding (It's sooner than you think)
          - WHY - There's only one good "WHY"

WHO - genetic screening, health testing & prebreeding examination

      • Genetic Screening
          - "CHIC"

The Canine Health Information Center (CHIC), website: http://www.caninehealthinfo.org/, is a centralized canine health database, jointly sponsored by the Orthopedic Foundation for Animals (OFA) and the American Kennel Club (AKC) Canine Health Foundation (CHF). The CHIC Mission Statement is quite simply ''To provide a source of health information for owners,breeders, and scientists that will assist in breeding healthy dogs.'' The program was originally implemented in the fall of 2001 with eight pilot breeds participating. Today, over one-half of the AKC Parent Clubs have joined the CHIC, and >30,000 dogs have met the individual breed health testing requirements and been assigned CHIC numbers.

A CHIC number is issued when test results are entered into the database satisfying each breed specific requirement, and when the owner of the dog has opted to release the results into the public domain. The CHIC number itself does not imply normal test results, only that all the required breed specific tests were performed and the results made publicly available.

      • Pedigree analysis
          - Outcrossing, inbreeding, line breeding
          - Analysis of pedigree for known carriers
          - Inbreeding coefficients
      • Health Testing
          - "Clearances" – Varies from breed to breed
          - Some of the more common tests include
               a. CERF
               b. Hip Dysplasia Evaluation - OFA/PennHIP
               c. Elbow Dysplasia - OFA
               d. Luxating Patellas - OFA
               e. Cardiac Evaluation - OFA
               f. Thyroid Function - OFA
          - Serologic testing
               a. Brucella canis RCAT – high sensitivity, low specificity
               b. False positives common
               c. Confirm with AGID test
               d. Herpesvirus testing
      • Prebreeding examination
          - General physical examination
          - Reproductive examination – digital vaginal examination, examination of external gentalia
          - Verification of protection from infectious viral disease (immunizations are current or vaccination titers are protective)
          - Herpesvirus testing
          - Testing to ensure candidates are free from parasitic infections (heartworm disease and intestinal parasites
          - Prebreeding vaginal cultures
